Description
Technical Field
[0001] This utility model relates to the field of sanitary ware technology, and more specifically, to a disposable toilet brush. Background Technology
[0002] Disposable toilet brushes are a popular type of sanitary ware on the market. They are a modern cleaning tool designed to simplify the toilet cleaning process, improve hygiene standards, and reduce the bacterial growth and cross-contamination problems that traditional toilet brushes may cause. This toilet brush features a design that separates the brush head from the brush dryer. Each time it is used, the built-in clamping mechanism on the brush head holds the protrusions, thus achieving a zero-contact cleaning effect. The brush head is also replaceable, ensuring a cleaner and more contaminated result.
[0003] However, existing brush head designs typically use a spherical design for the protrusions on the brush head to achieve 360-degree rotation without dead angles, which also has certain drawbacks. When cleaning the toilet, if there are stains that are difficult to remove, repeated wiping back and forth is necessary. However, since the holding device built into the brush handle relies on a spring for fixation, the brush head may detach due to the instability of the spring when too much force is applied. This makes it inconvenient to use and may also cause the brush head to clog the toilet drain. Therefore, it is necessary to design a disposable toilet brush that prevents detachment. Utility Model Content

[0006] A clamping mechanism is installed at the bottom of the lower brush rod, and the clamping mechanism is connected to the sliding mechanism through a connecting rod and a trigger block;
[0007] A fixed frame is fixedly installed on the inner wall of the bottom end of the lower brush rod. A moving plate is provided on the side of the fixed frame. A positioning pin is fixedly installed on the side of the moving plate near the clamping mechanism. The other end of the positioning pin is located inside the clamping mechanism. A limit rod is fixedly installed on the side of the moving plate. The end of the limit rod passes through the fixed frame. A nylon rope is fixedly installed on the side of the moving plate. A movable block is movably installed on the upper part of the lower brush rod. One end of the nylon rope is connected to the moving plate. The other end of the nylon rope passes through the fixed frame and extends upward to be fixedly connected to the movable block. A second spring is elastically connected to the outer surface of the nylon rope between the moving plate and the fixed frame. A pin mechanism is provided on the surface of the lower brush rod.
[0008] As a preferred embodiment of this utility model, the sliding mechanism includes a slider movably sleeved inside the compartment, a wedge fixedly installed at one end of the button inside the upper brush rod, a crossbar movably sleeved inside the button, one end of the crossbar passing through the button and fixedly connected to the inner wall of the upper brush rod, a first spring elastically connected inside the button between the crossbar and the inner wall of the button, and a third spring elastically connected between the slider and the lower brush rod.
[0009] As a preferred technical solution of this utility model, the clamping mechanism includes a clamping block rotatably mounted on the bottom end of the lower brush rod via a first rotating rod, a second inclined block fixedly mounted on the top of the clamping block, a trigger block movably mounted above the second inclined block, a connecting rod fixedly mounted above the trigger block, and the top of the connecting rod fixedly connected to the slider.
[0010] As a preferred embodiment of this utility model, the side of the second inclined block is provided with a positioning hole, and the other end of the positioning pin is located in the positioning hole of the second inclined block.
[0011] As a preferred technical solution of this utility model, the pin fixing mechanism includes a sliding groove, an upper groove and a lower groove formed on the surface of the lower brush rod. The upper groove and the lower groove are respectively located on the upper and lower sides of the sliding groove, and a lever passing through the lower groove is fixedly installed on the side of the movable block.
[0012] As a preferred embodiment of this utility model, there are two inclined blocks, and a spring sheet is fixedly connected between the two inclined blocks.
[0013] As a preferred embodiment of this utility model, a storage door is rotatably installed inside the bin via a second rotating rod, and a storage cylinder located inside the bin is fixedly installed on the side of the storage door. Magnetic blocks are provided on the top of the storage door and the top of the inner cavity of the bin.
[0014] As a preferred embodiment of this utility model, a fixing rod for supporting the lower brush rod is fixedly installed on the side of the storage cylinder.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. This utility model, by setting a positioning pin, a nylon rope, and a lever, allows the positioning pin to move closer to the second inclined block under the elastic force of the second spring and eventually insert into the pre-drilled hole inside the second inclined block, thereby limiting its position. Through the positioning engagement between the positioning pin and the second inclined block, the second inclined block is positioned after clamping the brush head, preventing the second inclined block from loosening due to excessive force when cleaning the toilet. The positioning pin restricts the rotation of the second inclined block, ensuring its stability under force and preventing the brush head from detaching from the second inclined block, thus avoiding clogging the toilet drain and facilitating its use by residents.
[0017] 2. The design of this utility model, through the magnetic block, allows for better closure between the compartment door and the compartment box. The magnetic attraction of the magnetic block prevents the compartment door from accidentally rotating and opening, making it more convenient. When using it, you only need to gently push the bottom of the compartment door to open it. Due to the design of the fixing rod, the lower brush rod can be supported and suspended after being inserted into the compartment box. At the same time, it is conducive to the internal ventilation and drying of the lower brush rod to prevent bacterial growth. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] like Figures 1 to 9 As shown, this utility model provides a disposable toilet brush, including a container 1, a lower brush rod 2 inserted into the top of the container 1, an upper brush rod 3 installed on the top of the lower brush rod 2, a button 4 movably embedded in the surface of the upper brush rod 3, and a sliding mechanism located on the side of the button 4 installed inside the container 1.
[0030] A clamping mechanism is installed at the bottom of the lower brush rod 2. The clamping mechanism is connected to the sliding mechanism through the connecting rod 13 and the trigger block 12.
[0031] A fixed frame 15 is fixedly installed on the inner wall of the bottom end of the lower brush rod 2. A moving plate 16 is provided on the side of the fixed frame 15. A positioning pin 17 is fixedly installed on the side of the moving plate 16 near the clamping mechanism. The other end of the positioning pin 17 is located inside the clamping mechanism. A limit rod 18 is fixedly installed on the side of the moving plate 16. The end of the limit rod 18 passes through the fixed frame 15. A nylon rope 19 is fixedly installed on the side of the moving plate 16. A movable block 21 is movably installed on the upper part of the lower brush rod 2. One end of the nylon rope 19 is connected to the moving plate 16. The other end of the nylon rope 19 passes through the fixed frame 15 and extends upward to be fixedly connected to the movable block 21. A second spring 20 located between the moving plate 16 and the fixed frame 15 is elastically connected to the outer surface of the nylon rope 19. A fixed pin mechanism is provided on the surface of the lower brush rod 2.
[0032] After clamping, the resident pulls the lever 25, causing it to disengage from the upper groove 23 and move downwards into the lower groove 24 within the sliding groove 22. At this time, the movable block 21 moves downwards along with the lever 25, causing the nylon rope 19 to move downwards. Under the elastic force of the second spring 20, the positioning pin 17 moves towards the position of the inclined block 11 and finally inserts into the pre-drilled hole inside the inclined block 11, thus limiting its position. Through the positioning engagement between the positioning pin 17 and the inclined block 11, the inclined block 11 is positioned after clamping the brush head, preventing it from loosening due to excessive force when cleaning the toilet. The positioning pin 17 restricts the rotation of the inclined block 11, ensuring its stability under force and preventing the brush head from detaching from the inclined block 11, thereby avoiding clogging the toilet drain and facilitating the resident's use.
[0033] The sliding mechanism includes a slider 5 movably sleeved inside the compartment 1, a wedge 6 fixedly installed at one end of the button 4 inside the upper brush rod 3, a crossbar 7 movably sleeved inside the button 4, one end of the crossbar 7 passing through the button 4 and fixedly connected to the inner wall of the upper brush rod 3, a first spring 8 elastically connected inside the button 4 between the crossbar 7 and the inner wall of the button 4, and a third spring 31 elastically connected between the slider 5 and the lower brush rod 2.
[0034] When the resident presses down on the first spring 8, the first spring 8 is pressed down into the interior of the upper brush rod 3, causing the inclined block 6 to contact and squeeze the slider 5. Since the contact surface between the inclined block 6 and the slider 5 is designed with an incline, the slider 5 moves downward as a whole. At this time, the horizontal bar 7 moves upward relative to the button 4 and squeezes the first spring 8 to put it in a state of elastic compression, which is used as the working trigger part of the clamping mechanism.
[0035] The clamping mechanism includes a clamping block 10 rotatably mounted at the bottom end of the lower brush rod 2 via a first rotating rod 9, a second inclined block 11 fixedly mounted on the top of the clamping block 10, a trigger block 12 movably mounted above the second inclined block 11, a connecting rod 13 fixedly mounted above the trigger block 12, and the top of the connecting rod 13 fixedly connected to the slider 5.
[0036] When slider 5 moves downward, it will drive connecting rod 13 downward. Through connecting rod 13, trigger block 12 moves downward together and squeezes the ends of two inclined blocks 11, causing clamping block 10 to rotate around the first rotating rod 9 until it opens at the bottom. Then, the user inserts the bottom end of the lower brush rod 2 into the brush head protrusion inside the storage cylinder 27. After that, the user releases button 4. Due to the elasticity of the first spring 8 and the third spring 31, slider 5 moves upward to reset. A fixed block is fixedly installed inside the lower brush rod 2 above the trigger block 12 to limit the upward movement distance of connecting rod 13. At the same time, under the action of spring plate 14, the two inclined blocks 11 rotate in opposite directions, clamping the brush head through clamping block 10. This achieves the clamping effect of the brush head, so that the user can operate the brush head to clean the toilet by holding the storage box 1 and the lower brush rod 2 as a whole, achieving zero-contact cleaning and making it more hygienic.
[0037] The inclined block 11 has a positioning hole on its side, and the other end of the positioning pin 17 is located in the positioning hole of the inclined block 11.
[0038] Due to the design of the positioning hole, the positioning pin 17 and the inclined block 11 are positioned together, so that after the inclined block 11 clamps the brush head, it is positioned by the positioning pin 17, which prevents the inclined block 11 from loosening due to excessive force when cleaning the toilet.
[0039] The pin mechanism includes a sliding groove 22, an upper groove 23, and a lower groove 24 formed on the surface of the lower brush rod 2. The upper groove 23 and the lower groove 24 are located on the upper and lower sides of the sliding groove 22, respectively. A lever 25 that passes through the lower groove 24 is fixedly installed on the side of the movable block 21.
[0040] The design of sliding groove 22, upper groove 23 and lower groove 24 allows for the control of the positioning engagement switch between positioning pin 17 and inclined block 11 above the lower brush rod 2, preventing excessive contact between the hand and the contaminated lower brush rod 2 at the bottom, making it more convenient to use.
[0041] There are two inclined blocks 11, and a spring sheet 14 is fixedly connected between the two inclined blocks 11.
[0042] Due to the design of the spring plate 14, after the trigger block 12 is disengaged from the inclined block 11, the two inclined blocks 11 rotate in opposite directions under the elastic force of the spring plate 14 to clamp the brush head.
[0043] The bin 1 has a bin door 26 rotatably mounted inside via a second rotating rod 28. A storage cylinder 27 located inside the bin 1 is fixedly mounted on the side of the bin door 26. Magnetic blocks 30 are provided on the top of the bin door 26 and the top of the inner cavity of the bin 1.
[0044] The design of the magnetic block 30 allows for better closure between the compartment door 26 and the compartment box 1. The magnetic attraction of the magnetic block 30 prevents the compartment door 26 from accidentally rotating and opening, making it more convenient. When in use, simply push the bottom of the compartment door 26 gently to open it.
[0045] The storage cylinder 27 has a fixed rod 29 for supporting the lower brush rod 2.
[0046] Due to the design of the fixing rod 29, the lower brush rod 2 can be supported and suspended after being placed inside the compartment 1, which also facilitates internal ventilation and drying of the lower brush rod 2 to prevent bacterial growth.
[0047] Working principle and usage process of this utility model:
[0048] First, the resident installs the storage box 1 on the bathroom wall and fills the storage cylinder 27 with brush heads. Then, the lower brush rod 2 is inserted into the storage box 1. When needed, the resident pulls the lower brush rod 2 upward and pushes the storage door 26 to rotate around the second rotating rod 28, causing the brush head to protrude. Then, the resident presses down on the first spring 8. When the first spring 8 is pressed down into the upper brush rod 3, the inclined block 6 contacts and squeezes the slider 5. Since the contact surface between the inclined block 6 and the slider 5 is designed with an incline, the slider 5 moves downward as a whole. At this time, the horizontal bar 7 moves upward relative to the button 4 and squeezes the first spring 8, putting it in a state of elastic compression.
[0049] When the slider 5 moves downward, it will drive the connecting rod 13 to move downward. The connecting rod 13 causes the trigger block 12 to move downward together and squeeze the ends of the two inclined blocks 11. The clamping block 10 rotates around the first rotating rod 9 and opens at the bottom. Then, the user inserts the bottom end of the lower brush rod 2 into the brush head protrusion inside the storage cylinder 27. Then, the user releases the button 4. Due to the elasticity of the first spring 8 and the third spring 31, the slider 5 moves upward to the reset position. At the same time, under the action of the spring plate 14, the two inclined blocks 11 rotate in opposite directions and clamp the brush head through the clamping block 10.
[0050] After clamping, the resident pulls the lever 25, causing it to disengage from the upper groove 23 and move downwards into the lower groove 24 within the sliding groove 22. At this time, the movable block 21 moves downwards along with the lever 25, causing the nylon rope 19 to move downwards. Under the elastic force of the second spring 20, the positioning pin 17 moves towards the position of the inclined block 11 and finally inserts into the pre-reserved hole inside the inclined block 11, thereby limiting its position. Through the positioning engagement between the positioning pin 17 and the inclined block 11, the inclined block 11 is positioned by the positioning pin 17 after clamping the brush head, preventing the inclined block 11 from loosening due to excessive force when cleaning the toilet.
